Application

Chlorobis(trimethylsilyl)methane can be used as a reagent for the preparation of:
  • Para-bis(trimethylsilyl)ethylstyrene (PBTES) monomer, which is used to synthesize corresponding network polymer of styrene.
  • Bis(trimethylsilyl)methyl magnesium chloride (Grignard reagent), which is used in the synthesis of bis(trimethylsilyl) allyl compounds by reacting with alkenyl bromide via the Kumada coupling reaction.
  • N-[Bis(trimethylsilyl)methyl]heterocumulenes.
